The root cause here is, with IO alignment feature enables, in worst case, we need F2FS_IO_SIZE() free blocks space for single one 4k write due to IO alignment feature will fill dummy pages to make IO being aligned.
So we will easily run out of free segments during non-inline directory's data writeback, even in process of foreground GC.
In order to fix this issue, I just propose to reserve additional free space for IO alignment feature to handle worst case of free space usage ratio during FGGC.

Pull f2fs updates from Jaegeuk Kim: "In this cycle, we've applied relatively small number of patches which fix subtle corner cases mainly, while introducing a new mount option to be able to fragment the disk intentionally for performance tests.
Enhancements:
- add a mount option to fragmente on-disk layout to understand the performance
- support direct IO for multi-partitions
- add a fault injection of dquot_initialize
Bug fixes:
- address some lockdep complaints
- fix a deadlock issue with quota
- fix a memory tuning condition
- fix compression condition to improve the ratio
- fix disabling compression on the non-empty compressed file
- invalidate cached pages before IPU/DIO writes
And, we've added some minor clean-ups as usual"

f2fs: introduce fragment allocation mode mount option
Added two options into "mode=" mount option to make it possible for developers to simulate filesystem fragmentation/after-GC situation itself. The developers use these modes to understand filesystem fragmentation/after-GC condition well, and eventually get some insights to handle them better.
"fragment:segment": f2fs allocates a new segment in ramdom position. With this, we can simulate the after-GC condition. "fragment:block" : We can scatter block allocation with "max_fragment_chunk" and "max_fragment_hole" sysfs nodes. f2fs will allocate 1..<max_fragment_chunk> blocks in a chunk and make a hole in the length of 1..<max_fragment_hole> by turns in a newly allocated free segment. Plus, this mode implicitly enables "fragment:segment" option for more randomness.

Merge tag 'f2fs-for-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "In this cycle, we've addressed some performance issues such as lock contention, misbehaving compress_cache, allowing extent_cache for compressed files, and new sysfs to adjust ra_size for fadvise.
In order to diagnose the performance issues quickly, we also added an iostat which shows the IO latencies periodically.
On the stability side, we've found two memory leakage cases in the error path in compression flow. And, we've also fixed various corner cases in fiemap, quota, checkpoint=disable, zstd, and so on.
Enhancements: - avoid long checkpoint latency by releasing nat_tree_lock - collect and show iostats periodically - support extent_cache for compressed files - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL) - report f2fs GC status via sysfs - add discard_unit=%s in mount option to handle zoned device
Bug fixes: - fix two memory leakages when an error happens in the compressed IO flow - fix commpress_cache to get the right LBA - fix fiemap to deal with compressed case correctly - fix wrong EIO returns due to SBI_NEED_FSCK - fix missing writes when enabling checkpoint back - fix quota deadlock - fix zstd level mount option
In addition to the above major updates, we've cleaned up several code paths such as dio, unnecessary operations, debugfs/f2fs/status, sanity check, and typos"
